Flux and Gauss's Law For a given charge distribution, the electric field can be calculated using Coulomb's Law. There are two possible methods: Calculate the field vectors due to all the charges and then add them vectorially, or first calculate the electric potential V due to these charges and take its negative gradient. For more information on this subject, see the Electric Potential module. There exists an alternate method to finding the electric field, which is provided by Gauss's Law. This "new" method is much more elegant and powerful when there is a certain symmetry to the physical situation--for example, when a charge distribution is spherically sy
